摘要
2010年,我们进行了水稻施用钾肥的试验研究,探讨新宾地区水稻施用钾肥的最佳施肥数量以及施肥方法,试验结果表明,新宾地区水稻施用钾肥,有改善产量构成因素、促进早熟、增强抗逆性等作用,进而提高水稻产量和品质。新宾地区水稻施用钾肥,最佳施用数量为施用硫酸钾12 kg/667 m2,缺钾的地块可以适当多施,不缺钾的地块可以适当少施。根据水稻需钾规律,钾肥可以做基肥和蘖肥施用。
The best fertilizing amount and method of K fertilizer were discussed by the test in Xinbin in 2010,the results indicated that the K fertilizer can inproved the yield components,promote prematurity,enhance stress tolerance and then increase the yield and quality.The best amount of potassium sulfate was 12 kg/667 m2 and it should fertilize in a variety of soil fertility.On the basis of potassium requirement,it could fertilize as base fertilizer and tiller fertilizer.
